Add a nice way of editing auto-generated installation instructions on PyPi packages.

Feature Description

I would like the ability to change the generated installation instructions, as using them directly does not work in my case, as the package in question relies on other packages it must find on PyPi and using:

pip install --index-url https://url/to/my/instance/ package-name

Will correctly install the base package but fail to install its dependencies defined in its pyproject.toml, with pip stating it cannot find matching distributions for them as it is searching only on the given URL. Adding PyPi's URL as --extra-index-url before the package name resolves this for example and I would like that to be stated in its installation instructions or even change them all together, etc.

Could you provide some formal commands and/or code? Then we could update this tmpl file:

It could be that I use it wrongly, but what works for me is:

pip install --index-url https://my/gitea/instance/api/packages/pypi/simple --extra-index-url https://pypi.org/simple package

This then installs my package from my gitea instance and then pulls its dependencies from pypi.
